I can't post links but there's what looks to be a thorough summary of mucuna research on examine.com - look for 'Mucuna Pruriens'

Among other things this says a rat study found that "low dose Mucuna paired with benserazide (peripheral dopa-decarboxylase inhibitor) was able to suppress symptoms associated with Parkinsons while low dose Levodopa + Benserazide was not"

Has anyone taken mucuna with benserazide?

Also, is it possible to buy mucuna ready roasted?
